MAX4314EEE+T

Video Amps And Modules Overview

The MAX4314EEE+T is a high-speed, low-power video multiplexer-amplifier from the MAX4310–MAX4315 family. It integrates a 4-channel analog multiplexer with a fixed +2V/V gain amplifier. The device operates on a single supply of +4V to +10.5V or dual supplies of ±2V to ±5.25V. Key electrical specifications include a 127MHz -3dB bandwidth and a 430V/µs slew rate. It features a 40ns channel switching time with ultra-low 10mVp-p switching transients. The unit is housed in a 16-pin QSOP package and supports an operating temperature range of -40°C to +85°C.

Video Amps And Modules Feature Summary

• Integrates a 4-channel multiplexer with a fixed +2V/V gain amplifier optimized for driving back-terminated cables
• Features rail-to-rail outputs that drive loads down to within 730mV of the supply rails
• Includes a low-power shutdown mode that reduces quiescent current to 560µA and places outputs in a high-impedance state
• Provides excellent video performance with differential gain error of 0.09% and differential phase error of 0.03°

Video Amps And Modules Applications

• Video signal multiplexing and crosspoint switching
• Driving 75Ω video cables with back-termination
• Flash ADC input buffering for high-speed data acquisition
• Broadcast video systems requiring high-fidelity signal routing
• Medical imaging equipment and multimedia products

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the datasheet revision matches the required design specifications. Ensure the supplier provides official documentation for the MAX4314EEE+ variant to validate the fixed-gain configuration and package type.

Video Amps And Modules Selection Notes

Select the MAX4314EEE+T when a fixed +2V/V gain is required for driving terminated video lines. Choose this part over adjustable-gain variants if internal feedback network stability is preferred. Consider the 16-pin QSOP footprint for board layout constraints. Verify that the 127MHz bandwidth meets the system's frequency requirements.

Video Amps And Modules Part Context

This component belongs to the MAX4310–MAX4315 series of single-supply mux-amps. The MAX4314 specifically differentiates itself by combining a 4-channel multiplexer with a fixed +2V/V amplifier. This distinguishes it from the MAX4311, which offers adjustable gain, and the MAX4315, which provides 8 channels. The series is designed for applications demanding high speed and low power consumption.

Video Amps And Modules Replacement Considerations

The MAX4314ESD serves as a pin-compatible alternative in a 14-pin Narrow SO package. Designers must account for the pin count difference and potential layout changes when substituting between the QSOP and Narrow SO packages. Functionality remains identical regarding the 4-channel multiplexing and fixed gain.
